replacing part lead water pipe with MDPE while fitting cloakroom toilet

Hey guys, whiles getting the toilet pipe routed to under the stairs the builder said that we have LEAD water pipes. as he will be tiling the toilet its best that he changes the water pipe going from under the stairs to the front door with 25MM MDPE for now. And in time the rest can be changed over. does this sound OK? its about 7 meters from the stopcock to the front door and another 8 meters from the front door to the boundary on the pavement. I guess he doesn't wish to do all the digging and I don't want to paying for that as well as the downstairs toilet. can anyone give me any advice?

its best to change to mdpe piping as they dont burst when frozen , they dont put lead into your water and lead pipes corrode and burst over time anyway , if you repair lead pipes the water pressure just finds the next weakest part of the pipe then bursts there. I used to replace lead pipes for the waterboard they were paying for the new plastic pipes from the stopcock in the pavement/road upto your boundary/ internal stopcock . it may be worth mentioning it to your local waterboard/authorities especially if the lead pipes are leaking as its actually their water leaking out and being wasted

Hi I work for The water board on the digging roads and footpaths and replacing old broken water pipes. It could be that your plumber is looking out for your best interests and replacing your water pipes now so maybe in the future saving you a headache if you discover a leak on the old lead pipe. On the other hand you could mayber go another 50 years and have no problems with your old lead pipes! Ask how much he plans to do all this extra work if you want it done. Don't forget you can always get this work done in the future at a time of your choosing. I know that in the Certain areas if a customer replaced there pipes in there garden The water board would then free of charge change all the pipe from the stopcock to the water main out in the road. If you do get this done phone your water area provider and ask them if they are running a lead free replacement scheme. ( which is exactly what I just mentioned before)

So far he's going to need to route the gas pipes under the floor board, and the stopcock is on the wall which he'll need to move further under the stairs so its behind the toilet. so you'd open the smaller door (which he'll make) to access the gas meter and water cockstop.

the house was built around 1890s, according to the house floor plan how far would you say the lead pipe would go into the house?
